1		# DomainDig – Project Context
2
3		## What this is
4		An iOS utility app for querying DNS records, inspecting SSL/TLS certificates,
5		checking HTTP headers, measuring TCP reachability, geolocating IP addresses,
6		analyzing email security records, tracing redirect chains, performing reverse
7		DNS lookups, and scanning common ports for any domain. Designed for developers,
8		sysadmins, and anyone who manages or troubleshoots domains and servers.
9
10		## Target user
11		Technically literate adults — developers, IT/sysadmin, homelab enthusiasts.
12		Comfortable with terms like A record, CNAME, MX, TTL, and TLS. The UI should be
13		clean and information-dense, not hand-holding.
14
15		## Design principles
16		- Minimal, utilitarian UI — this is a tool, not a consumer app
17		- Results should be readable at a glance — use clear labels, monospace where
18		appropriate for IPs and raw values
19		- Dark mode preferred as the primary aesthetic
20		- No onboarding, no tutorials, no splash screens
21		- Fast — results should appear as soon as they're available, not after all
22		lookups complete
23		- Each result section loads independently with its own ProgressView
24		- Errors shown inline per-section, never as global alerts
25
26		## Features
27
28		### DNS Lookup
29		Query the following record types for any domain via DNS-over-HTTPS (use
30		Cloudflare 1.1.1.1 — https://cloudflare-dns.com/dns-query):
31		- A
32		- AAAA
33		- MX
34		- NS
35		- TXT
36		- CNAME
37
38		Display each record type in its own section. Show TTL alongside each result.
39		If a record type returns no results, show "No records found" for that type
40		rather than hiding the section entirely.
41
42		After the apex query, also queries `*.{domain}` for A, AAAA, MX, and TXT.
43		Wildcard results are shown as a sub-section beneath each record type, labelled
44		with `*.{domain}`. Hidden if no wildcard records are returned.
45
46		### SSL/TLS Certificate Check
47		Connect to the domain on port 443 via URLSession and inspect the server's
48		certificate chain using URLSession delegate methods. Display:
49		- Common name (CN)
50		- Subject Alternative Names (SANs)
51		- Issuer
52		- Valid from / Valid until dates
53		- Days until expiry — highlight in red if under 30 days, yellow if under 60
54		- Certificate chain depth
55
56		### HTTP Headers Check
57		Fire a HEAD request to `https://{domain}` and display all response headers.
58		Header names in cyan, values in primary. Security-relevant headers highlighted
59		in yellow: `strict-transport-security`, `x-frame-options`,
60		`x-content-type-options`, `content-security-policy`, `referrer-policy`.
61		Service: `HTTPHeadersService.swift`.
62
63		### Reachability / TCP Latency
64		Use `NWConnection` (Network framework) to attempt TCP connections on ports 443
65		and 80. Measure time to `.ready` state. Display green/red dot, latency in ms,
66		and reachable/unreachable status. Timeout after 5 seconds.
67		Service: `ReachabilityService.swift`.
68
69		### IP Geolocation with Map
70		After DNS A record resolves, take the first IP and query
71		`https://ipapi.co/{ip}/json/` for country, region, city, org, lat/lon.
72		Display in an "IP Location" section with a SwiftUI `Map` (MapKit) centered on
73		the coordinates with a `Marker`. Map height 180pt, `.standard` style.
74		Service: `IPGeolocationService.swift`.
75
76		### Email Security Analysis
77		Parse SPF from existing TXT records (no extra query). Query `_dmarc.{domain}`
78		for DMARC and try common DKIM selectors (`default`, `google`, `mail`) via DoH.
79		Display green checkmark if found, red ✗ if not. Full record values truncated
80		to 80 chars with tap-to-expand. Triggered after DNS completes.
81		Service: `EmailSecurityService.swift`.
82
83		### Reverse DNS / PTR Lookup
84		After DNS A record resolves, construct reverse DNS name (reversed octets +
85		`.in-addr.arpa`) and query PTR record via Cloudflare DoH. Displayed inline
86		in the DNS Records section below the A record sub-section.
87		Service: `ReverseDNSService.swift`.
88
89		### Redirect Chain
90		Fire HTTP request to `http://{domain}` with redirects disabled. Follow up to
91		10 redirects manually, recording each hop's URL and status code. Display step
92		number, status code in cyan, URL, and "(final)" on the last hop. Shows
93		"No redirects — direct connection" if the first request returns 200.
94		Service: `RedirectChainService.swift`.
95
96		### Common Port Scanner
97		Probe 10 common ports (21/FTP, 22/SSH, 25/SMTP, 80/HTTP, 443/HTTPS,
98		587/SMTP-TLS, 3306/MySQL, 5432/PostgreSQL, 8080/HTTP-Alt, 8443/HTTPS-Alt)
99		using `NWConnection` with 3-second timeout. All probes run concurrently.
100		Green dot for open, grey dot for closed. Closed is expected — no error shown.
101		Service: `PortScanService.swift`.
102
103		### Results layout
104		- Domain input at the top — large text field, keyboard shows on launch
105		- Run button to trigger all lookups simultaneously
106		- Results displayed in clearly separated sections:
107		Reachability → Redirect Chain → DNS Records (with PTR inline) →
108		Email Security → SSL/TLS Certificate → HTTP Headers → IP Location →
109		Open Ports
110		- Each section loads independently — don't block one section waiting for another
111		- Email security, PTR, and IP geolocation are chained after DNS; all others
112		run in parallel
113
114		### Recent searches
115		Store the last 20 searched domains locally using UserDefaults. Display them as
116		a tappable list below the text field when no results are showing. Tapping a
117		recent domain populates the text field and runs the lookup immediately. Include
118		a "Clear" button to wipe history. Most recent at the top.
119
120		### Saved domains
121		Bookmark button (SF Symbol: `bookmark` / `bookmark.fill`) in the results
122		toolbar area, next to the share button. Tapping saves/unsaves the current
123		domain. Filled icon when saved. Saved domains viewable from a toolbar button
124		that pushes to `SavedDomainsView` — a list of saved domains, tappable to run
125		lookups, with swipe-to-delete and an Edit button for bulk deletion.
126		Persisted in UserDefaults under key `savedDomains`.
127
128		### Lookup history with cached results
129		After each successful lookup, a snapshot of all results (DNS, SSL, HTTP headers,
130		reachability, geolocation, email security, PTR, redirect chain, port scan) is
131		saved to history in UserDefaults as JSON. Capped at 50 entries. `HistoryView`
132		shows past lookups with domain and timestamp. Tapping shows full cached results
133		in `HistoryDetailView` using the same layout, labelled as cached with the
134		original timestamp. Model: `HistoryEntry` (Codable).
135
136		### Share / export
137		A share button (SF Symbol: `square.and.arrow.up`) in the top-right of the
138		results area. Formats the full results as plain text and presents the iOS share
139		sheet via UIActivityViewController. The export includes: domain, timestamp,
140		reachability, redirect chain, all DNS records with TTLs and PTR, email security
141		records, SSL cert fields, HTTP headers, IP geolocation data, and port scan
142		results.
143
144		## Technical constraints
145		- SwiftUI, iOS only
146		- Fully offline except for network requests (DNS-over-HTTPS, SSL, HTTP HEAD,
147		TCP connections, geolocation API)
148		- No accounts, no analytics, no ads
149		- No third-party dependencies — URLSession, Network, MapKit only
150		- Targets latest iOS
151
152		## Architecture
153		- `Models.swift` — All data models (DNS, SSL, HTTP headers, reachability,
154		geolocation, history entry), all Codable for persistence
155		- `DomainViewModel.swift` — `@Observable` view model orchestrating all lookups,
156		managing state, history, saved domains, recent searches, and export
157		- `ContentView.swift` — Main screen with input, all result sections, toolbar
158		- `SavedDomainsView.swift` — Saved domains list with edit/delete
159		- `HistoryView.swift` — History list + `HistoryDetailView` for cached results
160		- Services: `DNSLookupService`, `SSLCheckService`, `HTTPHeadersService`,
161		`ReachabilityService`, `IPGeolocationService`, `EmailSecurityService`,
162		`ReverseDNSService`, `RedirectChainService`, `PortScanService`
163
164		## What good looks like
165		A developer pastes a domain, taps run, and within a couple of seconds sees a
166		clean breakdown of TCP reachability, redirect chain, every DNS record type with
167		reverse DNS, email security posture, the full SSL cert status, HTTP response
168		headers with security headers highlighted, IP geolocation with a map, and a
169		port scan of common services. It should feel like a native, polished version of
170		running `dig`, `openssl s_client`, `curl -I`, `nmap`, and `whois` from the
171		terminal.
