IOS Build Crash #4
Description
Bug Description
My target is build simple IOS app using with fetch any example api url, use gea store for fetched data and render store data tsx template.
I developed and build for web. It's working well. But IOS build is crashed. I tried remove features step by step but still have issues on IOS build.
I tried some solution. When you replace fetchResponse.json() to fetchResponse.text() and parse JSON different way and it's building. But still have issues.
Steps to Reproduce
- Create a new gea:
gea create simple-app - Choose:
Blank application - Choose:
Web browser - Use my source code below
- Change package.json ios target from false to true.
- Set icons to package.json file.
- Install apple package.
npm i @geastack/apple - Build app:
npx gea build --target ios
Expected Behavior
CLI should build without error and When I run app on IOS device should be run without error.
Actual Behavior
While building IOS app CLI is crash and have error:

My Source Code
import { Component } from '@geastack/core'
type Item = {
userId: number,
id: number,
title: string,
completed: boolean,
};
const fetchTodos = async () => {
const fetchResponse = await fetch('https://jsonplaceholder.typicode.com/todos');
const data = (await fetchResponse.json()) as Item[];
}
export class App extends Component {
template() {
fetchTodos();
return (

I reproduced this with current packages (cli 0.1.107, core 0.1.46,
apple 0.2.16) and your source.
FetchResponse.jsonrefusal is fixed: core c33c945 bindsjson()through the compiler's JSON reader. It first shipped in
@geastack/geatsc-plugin-gea 0.1.9 on 2026-09-30, two days after this
report. The generated C++ now reads the body with
text()and parses it.Undefined symbols: "_gea_embedded_assets_prepare". That happens forevery iOS and macOS app without file-backed assets, including the blank
starter. Reference the prepare hook through GEA_PROGRAM_HOOK and clean up stale asset manifests core#75 fixes it.
fetchon iOS returns status 0 and an empty body, sojson()throwsUnexpected end of JSON input. iOS has no networkbackend yet; Render the weather example correctly on macOS and iOS apple#3 adds one. With core#75 and that file
applied locally, your request loaded and parsed on an iPhone 11.
