/ Since HTTP requests are async, the completion syntax is used. Otherwise, the behavior is the same as decode Object Of Class: for Key. set, or a subclass of any class in the set. / For this func call to work, the `wknd-shared/adventures-all` query must be deployed to the AEM environment/service specified by the host. To navigate the symbols, press Up Arrow, Down Arrow, Left Arrow or Right Arrow. / Returns all WKND adventures using the `wknd-shared/adventures-all` persisted query. The application uses two persisted queries: Persisted queriesįollowing AEM Headless best practices, the iOS application uses AEM GraphQL persisted queries to query adventure data. On the adventures list view, pull to refresh the data from AEM.īelow is a summary of how the iOS application is built, how it connects to AEM Headless to retrieve content using GraphQL persisted queries, and how that data is presented. Selecting an adventure opens the adventure details. code language-plainīuild the application using Xcode and deploy the app to iOS simulatorĪ list of adventures from the WKND site should be displayed on the application. The AEM_TOKEN is an access token that authenticates to an AEM user with access to WKND GraphQL content. The AEM_USERNAME and AEM_PASSWORD authenticate a local AEM user with access to WKND GraphQL content. If connecting to AEM Author, add the AEM_AUTH_TYPE and supporting authentication properties to the Config.xcconfig. Target hostname for AEM environment, do not include or AEM_HOST = The http/https protocol scheme used to access the AEM_HOST Modify the file Config.xcconfig file and update AEM_SCHEME and AEM_HOST to match your target AEM Publish service. $ git clone Xcode and open the folder ios-app Its a solution, definition not the only solution, and very likely not the best solution either.Clone the adobe/aem-guides-wknd-graphql repository: code language-shell Story too long for this margin to contain, but I'm using it to capture arbitrary JSON blobs as a sub-part of a generally strongly-typed Codable model. dataUsingEncoding:NSUTF8StringEncoding // Get NSString from NSData object in Base64. NSData nsdata 'iOS Developer Tips encoded in Base64'. (You may ask why on earth I needed to do that. I copy the code here, just in case: // Create NSData object. The error in my code is interesting in light of the ongoing discussion of typed throws over on Evolution: I was treating an entirely untyped throw as if I had the safety guarantees of a typed throw. Entirely my bad, as the contract doesn't make any claims whatsoever about what errors may be thrown on failure. Which didn't include this one, so my retry logic for when the probe fails didn't run. But I was using that call as a "probe" to see if I could decode an Int, and catching specific error cases that I knew about. Mostly that's fine, because mostly when you call decode(Int.self) the kind of failure doesn't much matter to you. Im not entirely sure if this will help, but quickly searching for how to unescape unicode characters in objective-c I found this DanZimm. The change in behaviour is, code(Int.self) when decoding a JSON literal such as 18.18 used to throw a DecodingError.dataCorrupted (saying "parsed JSON number does not fit in Int") it now throws a JSONError.numberIsNotRepresentableInSwift. Decode String with Emoji characters such as ud83d. It is a change in behaviour between iOS 16 and 17, but a rather subtle one that shortcuts in my own code happen to turn into the mess you see above.
