Swift Examples - Fal
Step 1
Add the AIProxySwift package to your Xcode project
- Open your Xcode project
- Select File > Add Package Dependencies
- Paste github.com/lzell/aiproxyswift into the package URL bar
- Click Add Package
Step 2
Initialize
Import AIProxy and initialize using the following code:
import AIProxy
let falService = AIProxy.falService(
partialKey: "partial-key-from-your-developer-dashboard",
serviceURL: "service-url-from-your-developer-dashboard"
)
Step 3
Setup DeviceCheck
Before adding the DeviceCheck ENV variable check these three things: 1) in Xcode check that your Apple developer team is selected under the 'Signing & Capabilities' tab 2) make sure the bundle ID of your app is explicit (i.e. it can't contain a wildcard) 3) make sure the bundle ID in Xcode matches a bundle ID listed on the Identifers page in the Apple Developer dashboard.
Add the AIPROXY_DEVICE_CHECK_BYPASS env variable to your Xcode project:
- Type cmd-shift-comma to open up the "Edit Schemes" menu
- Select Run in the sidebar
- Add to the "Environment Variables" section (not the "Arguments Passed on Launch" section) an env variable with name AIPROXY_DEVICE_CHECK_BYPASS and value that we provided you in the AIProxy dashboard.
How to generate a FastSDXL image using Fal
import AIProxy
let falService = AIProxy.falService(
partialKey: "partial-key-from-your-developer-dashboard",
serviceURL: "service-url-from-your-developer-dashboard"
)
let input = FalFastSDXLInputSchema(
prompt: "Yosemite Valley",
enableSafetyChecker: false
)
do {
let output = try await falService.createFastSDXLImage(input: input)
print("""
The first output image is at \(output.images?.first?.url?.absoluteString ?? "")
It took \(output.timings?.inference ?? Double.nan) seconds to generate.
""")
} catch AIProxyError.unsuccessfulRequest(let statusCode, let responseBody) {
print("Received non-200 status code: \(statusCode) with response body: \(responseBody)")
} catch {
print("Could not create Fal SDXL image: \(error.localizedDescription)")
}
