const wasmModulePath = '/wasm/AudioMusic_bg.wasm' 

async function instantiateArrayBuffer(binaryFile, imports) {

  try {

    const wasmModule = await WXWebAssembly.instantiate(wasmModulePath, imports)

    return wasmModule

  } catch(reason) {

    console.log('Failed to load wasm:' + reason)

    return undefined

  }

}

android真机和模拟器没有问题。iOS执行到WXWebAssembly.instantiate时崩溃，且console没有信息输出。
