Alex
AI coding support for iOS and Swift projects, integrated with the Xcode workflow.
About Alex
Alex places an AI coding assistant beside Xcode for iOS and Swift projects. Developers can discuss selected code or a whole codebase, apply changes, use tab completion and voice input, and generate Git commit messages. The build-and-fix action compiles the project, finds errors, applies corrections, then rebuilds until compilation succeeds. Chat also accepts images for interface analysis and code generation. A model selector covers multiple hosted models, OpenRouter, and custom private endpoints. Pro is $30 per month with 600 monthly chat credits; another 250 credits costs $12.50. Unlimited is $200 per month, has no monthly chat-credit cap, and works on one device. Monthly credits expire, while purchased top-ups roll over.

Best use cases
Fix repeated Xcode compilation errors in a build loop
Discuss selected code or the full codebase in chat
Turn interface images into implementation guidance and code
Compare before choosing
Pro costs less but caps monthly chat usage at 600 credits
Unlimited removes the monthly chat-credit cap but costs $200 per month
Both plans include unlimited code applies, tab completion, voice input, and Git commit generation
Features
Fix Xcode build errors
Build a project, detect compilation errors, apply fixes, and rebuild in a continuous loop until the project compiles.
Discuss code with project context
Start chat from selected code, add more selections to an existing conversation, or include the whole codebase for broader questions.
Generate code from visual references
Paste or drag images into chat to discuss interface designs, investigate visual bugs, and generate related code.
Pros
- The build-and-fix loop can repeatedly compile and repair errors, reducing manual iteration during Xcode debugging.
- Pro includes unlimited code applies, tab completion, voice input, and Git commit generation for a predictable $30 monthly fee.
- Support for hosted models, OpenRouter, and custom endpoints gives teams flexibility over model compatibility.
Cons
- Pro has a 600-credit monthly chat limit, and extra usage costs $12.50 for each 250-credit top-up.
- Monthly chat credits do not roll over, so unused included capacity expires at the end of the billing period.
- The $200 Unlimited plan is restricted to one device, which can complicate use across multiple Macs.
