Enter a valid API Key Apigee Configuration not found

[ApplyFrank]

Hi Ticket Master Devs,

I followed the instruction, got an API key, and signed the project with my own developer account. However, after building and clicking the table cells, I'm getting a "Enter a valid API Key" and in the console logs I see

apiKeyText: .backgroundTapped(value: <nil>)
discoveryAPIMenu: .backgroundTapped(value: <nil>)
Authentication Configuring...
 - Authentication Configuration Error: Apigee Configuration not found

I'm adding my apiKey like this
let apiKey: String = "consumer_key_from_exploreYourApps"

I must be doing something wrong, could you help me out? Thank you
