iCurlHTTP v1.19

What's New in v1.19

iCurlHTTP v1.19 includes a long-requested "Display Headers Only" option plus a broad set of App Store compliance, UI performance, and settings improvements.

Highlights

• Display Headers Only — a new Response Output setting that discards the response body (like curl -o /dev/null) and shows a one-line notice instead. Great for testing podcast/CDN endpoints without downloading large binaries. Requested in #7, implemented in #8.
• Fixed Width Font setting under Response Output — displays result output in a monospace font. Requested in #6.
• Override System Proxy setting under a new Proxy Settings section — manually set a custom proxy or force no proxy for testing. Requested in #3.
• Large File Warning threshold raised from 200KB to 2MB to match modern HTML page sizes. Requested in #5.
• Major UI performance fixes for large HTML responses: incremental NSTextStorage appends, throttled run-loop refresh, and allowsNonContiguousLayout so scrolling no longer lays out everything before the visible range.
• Adopted the iOS 13 UIScene lifecycle to address Apple's runtime warning.
• Raised the minimum deployment target to iOS 13.0, fixed curl API type mismatches, removed deprecated APIs (networkActivityIndicatorVisible, beginAnimations/commitAnimations, scrollIndicatorInsets), and cleaned up entitlements and encryption declarations for App Store validation.
• Added a test/proxy_server.py helper for manually testing the proxy override setting.
