What it does

Swiftui Backports is an agent skill from shaps80/SwiftUIBackports. Find SwiftUIBackports replacements for SwiftUI APIs unavailable on a project deployment target. Use for Swift/SwiftUI compiler availability errors, old iOS/tvOS/watchOS/macOS targets, or when implementing SwiftUI app features that may benefit from SwiftUIBackports.

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files.

It sits in Mobile, covering iOS development. It works with SwiftUI, iOS and macOS. The repository describes itself as: A collection of SwiftUI backports for iOS, macOS, tvOS and watchOS. The licence is MIT.

When your agent uses it

  • Swift/SwiftUI compiler availability errors
  • Old iOS/tvOS/watchOS/macOS targets
  • Implementing SwiftUI app features that may benefit from SwiftUIBackports

Example prompts

  • “/swiftui-backports”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Confirm the availability need.
  2. Check whether SwiftUIBackports is available.
  3. Search the index.
  4. Decide native vs backport.
  5. Use the discovered API.
  6. If no index match exists, say no backport was found and choose another compatibility path.

What it can do on your machine

Read from SKILL.md and the folder at commit eaeff42. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • rg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Swiftui Backports loads about 604 tokens when it runs, and up to ~8.4k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 248 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~604
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Find SwiftUIBackports replacements for SwiftUI APIs unavailable on a project deployment target. Use for Swift/SwiftUI compiler availability errors, old iOS/tvOS/watchOS/macOS targets, or when implementing SwiftUI app features that may benefit from SwiftUIBackports.

SwiftUI Backports

When SwiftUI API is newer than the deployment target, check the bundled backport index before hand-rolling compatibility code or raising the target.

Workflow

  1. Confirm the availability need.

    • Use this for compiler availability errors, planned use of modern SwiftUI APIs, or user requests to support older OS versions.
    • Find deployment target in Package.swift, .xcodeproj/project.pbxproj, .xcconfig, or target settings.

  2. Check whether SwiftUIBackports is available.

    • Search for SwiftUIBackports, SwiftBackports, or existing .backport usage.
    • If absent, suggest adding https://github.com/shaps80/SwiftUIBackports only when it fits the project. Do not add it unless asked.

  3. Search the index.

    • Use rg -i "<api-name>|<related-term>" references/Backports.jsonl first.
    • Read only matching JSONL records when possible; the first line is metadata, remaining lines are backport records.
    • Match by name first, then by kind and namespace.
    • If the project has an installed SwiftUIBackports checkout, you may confirm against its source when uncertain.

  4. Decide native vs backport.

    • If target platform is marked unavailable, do not suggest that backport.
    • If deployment target is lower than the entry's deprecated version, use or suggest the backport.
    • If deployment target is at or above deprecated, prefer native SwiftUI.

  5. Use the discovered API.

    • View modifiers: .backport.foo(...)
    • Types/views: usually Backport.Foo; use Backport<Any>.Foo if the compiler needs the fully qualified namespace.
    • Environment values: use the indexed environment key, such as @Environment(\.backportRequestReview).

  6. If no index match exists, say no backport was found and choose another compatibility path.

Do not implement new SwiftUIBackports APIs from this skill. This is for consuming the library.

    .backport.presentationDetents([.medium, .large])
