AppleのIn-Purchaseで課金テストをしたいのにプロダクトがエラーになってしまう場合のチェック項目

サクッとテストしたいのに

productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse)

でなぜか全てのプロダクトがinvalidProductIdentifiersになってしまう。
そんな場合は下記をチェック

• Have you enabled In-App Purchases for your App ID?
• Have you checked Cleared for Sale for your product?
• Have you submitted (and optionally rejected) your application binary?
• Does your project’s .plist Bundle ID match your App ID?
• Have you generated and installed a new provisioning profile for the new App ID?
• Have you configured your project to code sign using this new provisioning profile?
• Are you building for iPhone OS 3.0 or above?
• Are you using the full product ID when when making an SKProductRequest?
• Have you waited several hours since adding your product to iTunes Connect?
• Are your bank details active on iTunes Connect? (via Mark)
• Have you tried deleting the app from your device and reinstalling? (via Hector, S3B, Alex O, Joe, and Alberto)
• Is your device jailbroken? If so, you need to revert the jailbreak for IAP to work. (via oh my god, Roman, and xfze)

私の場合は、Are your bank details active on iTunes、要するに銀行口座の反映がされていなかった。(Banking Informationでみると24時間かかるみたい)
