## Version history (last 3 releases)

### 1.3.0 — 2026-08-26

iDeveloper v1.3.0 Major Update

Search is now a real workstation entry. Type once to land on a tool, handbook entry, or a common developer entity. Your Home Screen icon can match paper, dusk, or a terminal desk.

1. Global search is fully upgraded. One query searches tools, offline cheatsheets, Apple device models, HTTP status codes, MIME types, named colors, and SF Symbols, with results grouped by category.
2. Tap a hit to go straight there. Status codes and MIME types open the matching cheatsheet. Device models, colors, and symbols open the matching tool with the query already filled in.
3. Search is faster and more precise. Queries like 403, iPhone16,2, or json surface entity results first. You can still filter by All, Tools Only, or Cheatsheets Only.
4. New alternate app icons. Paper, Graphite, Dusk, Amber, and Cyan join Midnight and Terminal, for 8 icons in total. In Settings, Appearance, expand the list, tap a thumbnail to preview, and tap the name to switch.
5. Traditional Chinese cheatsheets read more naturally. The handbook now uses system-quality conversion, so body text and search glyphs stay consistent in Traditional Chinese.

We welcome your feedback in the app. If you enjoy this update, a rating and review on the App Store will help more developers find iDeveloper.

### 1.2.0 — 2026-08-14

iDeveloper v1.2.0 Major Update

1. New Device Models encyclopedia: look up about 255 Apple devices offline. Match identifiers, A-numbers, and marketing names in one place, and recognize This Device instantly.
2. Batch identify from logs: paste crash logs or identifier lists to extract multiple devices and copy the right strings faster.
3. Screen Sizes upgraded: browse by size or by model. Check points, scale, and pixels at a glance, with a This Device screen card.
4. Models and sizes connected: jump from a device profile to screen specs, or from a size list into device details for a smoother workflow.
5. Deeper links and smarter share: open a tool with search prefilled or a specific device entry. Shared text can also suggest Device Models.
6. Polish for layout and feedback: equal-height tool grids look cleaner. Feedback can include the marketing name, with a clear guide when system Mail is not set up.

We welcome your rating and feedback. Every suggestion helps us make iDeveloper better for developers like you. Thank you.
