/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/Project Templates/iOS/Application- Xcode templates (#1)~/Library/Developer/Xcode/Templates/– custom user templates (#2)
- Create a folder with the template's name in the (#2) folder. For example, UIKit App.xctemplate
- Copy there the most similar TemplateInfo.plist file from (#1) or create a new one
- Fill TemplateInfo.plist file parameters
- (Optional) Add template project files if needed. For example, some .swift files
- SortOrder – the order in the Xcode custom section with user templates
- Description – text description, possibly not used
- Concrete – YES, if we want to see a template in Xcode. NO if we're going to use a template just as an Ancestor for other templates
- Kind – for project templates we should use the Xcode.Xcode3.ProjectTemplateUnitKind value
- Identifier – a unique identifier
- NameOfInitialFileForEditor – a name of a file that will be opened after a project creating
- Ancestors – existing templates we want to inherit properties from
- Image – an icon in the Xcode custom section with user templates. It is OK to copy from an existing template
- Nodes – an array of items to create in a project
- Definitions – a dictionary with keys from Nodes elements. A value for every key is a dictionary with file parameters like Path and SortOrder. Without it, the file will be created empty
- Options – UI template parameters if needed. For example, if we should include Unit tests
- Targets – just a copy of the Cocoa Touch App Base.xctemplate value because I don't need it as an Ancestor template. Possibly, not required in other cases
- UIKit App – a UIKit application without a storyboard interface
