iOS

Min iOS version

Thermion requires a minimum iOS version of 13.0. When building a Flutter application, ensure your application’s ios/Podfile contains the following:

platform :ios, '13.0'

and in ios/Info.plist:

<key>LSMinimumSystemVersion</key>
<string>13.0</string>

When submitting to the App Store, you may encounter an error saying thermion_dart.framework does not supported the minimum deployment target in Info.plist.

This is because Flutter hardcodes a deployment target of iOS 12.0 when invoking the native assets build, which conflicts with actual requirement.

After running flutter build ios (but before archiving the build and submitting to the App Store), run the following script to replace the MinimumOSVersion:

#!/bin/zsh

# Array of directories containing Info.plist files
directories=(
    "./build/ios/iphoneos/Runner.app/Frameworks/thermion_dart.framework"
    "./build/ios/Release-iphoneos/Runner.app/Frameworks/thermion_dart.framework"
    "./build/native_assets/ios/thermion_dart.framework"
)

# Loop through each directory
for dir in "${directories[@]}"; do
    plist_path="$dir/Info.plist"

    # Check if Info.plist exists in the directory
    if [[ -f "$plist_path" ]]; then
        echo "Processing: $plist_path"

        # Use PlistBuddy to change the MinimumOSVersion
        /usr/libexec/PlistBuddy -c "Set :MinimumOSVersion 13.0" "$plist_path" 2>/dev/null

        if [[ $? -eq 0 ]]; then
            echo "✓ Successfully updated version to 13.0"
        else
            echo "✗ Failed to update version in $plist_path"
        fi
    else
        echo "✗ Info.plist not found in $dir"
    fi
done
