SCNSceneSource init is giving Ambiguous use of 'init(URL:options:)' error

问题

This init is giving me an error:

Ambiguous use of 'init(URL:options:)'

let sceneSource = SCNSceneSource(URL: url, options: [SCNSceneSourceAnimationImportPolicyKey : SCNSceneSourceAnimationImportPolicyDoNotPlay])!

Please help me understand what the issue is, and how I might go about fixing it. Thanks so much for any advice!

回答1:

You used uppercase letters in the URL parameter instead of lowercase. Replace

let sceneSource = SCNSceneSource(URL: url, options: [SCNSceneSourceAnimationImportPolicyKey : SCNSceneSourceAnimationImportPolicyDoNotPlay])!

with

let sceneSource = SCNSceneSource(url: url, options: [SCNSceneSourceAnimationImportPolicyKey : SCNSceneSourceAnimationImportPolicyDoNotPlay])!
