Swift & XCode

See separate page - there is bound to be other iOS development stuff in there too.

Creating icons

If you get an “invalid binary” error when trying to deploy, this might be because you haven’t created assets / icons yet.
SquareFillXCode (accessibile to Clare only) has icons for all contexts in SquareFillXCode\Assets.xcassets\
You can use Icon Set Creator to create icons.
- Upload a 1024x1024 version of your icon
- Select target (eg iOS)
- Click Go and select a location
  - probably best to put it somewhere other than the target project, then copy over what you need - see below
- It will create a folder containing an appropriate set of icons for you
  - Note that if you’ve selected “ios”, it will probably create a folder called ios
  - Within that will probably be a sub-folder called AppIcon.appiconset
  - That will contain a file, Contents.json, which maps each of the files to a context
  - That’s why the icon file names can all be based on your original file name (ie you don’t have to give the icon file a special name)
  - What you actually want is for the entire AppIcon.appiconset folder to go into your Assets.xcassets folder
  - If you already have an AppIcon.appiconset folder in there, just replace it with the new one.
