Get AutoId created in different swift file - ios

Question

Sorry about the lengthy post!
I have a UICollectionView with 2 cells (newJobCellGeneral & newJobCellTechnical).
I am writing data to Firebase from each cell using notifications. The data isn't written until a button is pressed on the second page of my UICollectionView.
When the button is pressed the notification activates the action in newJobCellGeneral that the writes data to Firebase using autoId.
What I want to do is reference the autoId created in newJobCellGeneral into my newJobCellTechnical action so when I reference the data later on I can group it all together as they will all have the same Id.
I am not sure if this is the best way to do this but it's the only way I can think it can be done as I am still new to Xcode & Firebase
Here the desired JSON setup I would like to create:
{
"jobInfo" : {
"-L61ATfMsTg1RH2T90tV" : {
"agencyName" : "Ben",
"directorName" : "Ben",
"jobBrand" : "Ben",
"jobName" : "Ben",
"prodCoName" : "Ben"
}
},
"jobTechnical" : {
"-L61ATfTZojWmlkB7paU" : {
"jobId" : "L61ATfMsTg1RH2T90tV"
"FPS" : "34",
"resolutionHeight" : "1080",
"resolutionWidth" : "1920"
}
},
"shots" : {
"-L61ATfTZojWmlkB7paV" : {
"frame_001" : {
"jobId" : "L61ATfMsTg1RH2T90tV"
"FPS" : "34",
"resolutionHeight" : "1080",
"resolutionWidth" : "1920"
},
"frame_002" : {
"jobId" : "L61ATfMsTg1RH2T90tV"
"FPS" : "34",
"resolutionHeight" : "1080",
"resolutionWidth" : "1920"
},
"frame_003" : {
"jobId" : "L61ATfMsTg1RH2T90tV"
"FPS" : "34",
"resolutionHeight" : "1080",
"resolutionWidth" : "1920"
}
}
}
}
Here is the UICollectionView:

Here is the newJobCellGeneral init (there are other things in here, just wanted to show the notification) and action (I wont upload the rest of the code because it's quite long - unless its required):
override init(frame: CGRect) {
super.init(frame: frame)
NotificationCenter.default.addObserver(self, selector: #selector(handleNewJobGeneral), name: NSNotification.Name(rawValue: "handleNewJobGeneral"), object: nil)
}
// HANDLE NEW JOB GENERAL
#objc func handleNewJobGeneral(){
let newJobBrand = jobBrand.text!
let newJobName = jobName.text!
let newDirectorName = directorName.text!
let newAgencyName = agencyName.text!
let newProdCoName = prodCoName.text!
// WHERE TO PUT IN DATABASE
let jobInfoReference = Database.database().reference().child("jobInfo")
let jobInfoChildRef = jobInfoReference.childByAutoId()
// REFERENCING DICTIONARY
let jobBrandValue = ["jobBrand": newJobBrand]
let jobNameValue = ["jobName": newJobName]
let jobDirectorValue = ["directorName": newDirectorName]
let jobAgencyNameValue = ["agencyName": newAgencyName]
let jobProdCoValue = ["prodCoName": newProdCoName]

Thank you for anyone who can help me get my head around this!
