Mixing
Swift request for Firebase database is taking 19 seconds
0
!! UPDATE: Firebase might not be the problem (data gotten in half a second it seems on ViewController main screen although connection may still be a hold up [?]; also, on AddUniversal screen, adding a new entity to Firebase database triggers the same delay, suggesting Firebase is the problem [?] as there's no sizing or collection view or much of anything on that screen) - on ViewController screen, I thought problem might lie somewhere between obtaining of data and plugging it into collectionView cells (cardviews) as per Brian Voong model of vertical sizing. I'll leave the original code below, and some of the Brian Voong stuff at the end. !!
I have tried removing encryption/decryption process, removing invocation of GoogleAppEngine (encryption key request), and removal of image (only text requested; probably under 200kB). I've also tried Frank van Puffelen's suggestion to add a "on" listener in addition to my "once" listeners. Nothing works. This app will be unusable for customers if I don't get it fixed.

There is nothing in the code you shared that would explain a 19s load time. If you want us to help, please share enough information for us to be able to reproduce the issue. I recommend checking out how to create a minimal, complete, verifiable example, as it contains many tips on isolating the problem.

Thanks. The problem has grown from 2 seconds to 19 seconds over time as I add more items to the database. There are currently 1,800 objects in the database, most of which are a set of 20 simple strings. My computer internet is horrible but I'll try to put together the minimum code you're asking for.

After doing some work with breakpoints, it seems that it IS getting the info from Firebase within a half a second or so; it must be taking the 19 seconds to render my cardviews or something. I thought I had a recyclerView kind of thing which only required about 5 cards to load at once. I will check this.

!! UPDATE: Firebase might not be the problem (data gotten in half a second it seems on ViewController main screen although connection may still be a hold up [?]; also, on AddUniversal screen, adding a new entity to Firebase database triggers the same delay, suggesting Firebase is the problem [?] as there's no sizing or collection view or much of anything on that screen) - on ViewController screen, I thought problem might lie somewhere between obtaining of data and plugging it into collectionView cells (cardviews) as per Brian Voong model of vertical sizing. I'll leave the original code below, and some of the Brian Voong stuff at the end. !!
I have tried removing encryption/decryption process, removing invocation of GoogleAppEngine (encryption key request), and removal of image (only text requested; probably under 200kB). I've also tried Frank van Puffelen's suggestion to add a "on" listener in addition to my "once" listeners. Nothing works. This app will be unusable for customers if I don't get it fixed.

!! UPDATE: Firebase might not be the problem (data gotten in half a second it seems on ViewController main screen although connection may still be a hold up [?]; also, on AddUniversal screen, adding a new entity to Firebase database triggers the same delay, suggesting Firebase is the problem [?] as there's no sizing or collection view or much of anything on that screen) - on ViewController screen, I thought problem might lie somewhere between obtaining of data and plugging it into collectionView cells (cardviews) as per Brian Voong model of vertical sizing. I'll leave the original code below, and some of the Brian Voong stuff at the end. !!
I have tried removing encryption/decryption process, removing invocation of GoogleAppEngine (encryption key request), and removal of image (only text requested; probably under 200kB). I've also tried Frank van Puffelen's suggestion to add a "on" listener in addition to my "once" listeners. Nothing works. This app will be unusable for customers if I don't get it fixed.

There is nothing in the code you shared that would explain a 19s load time. If you want us to help, please share enough information for us to be able to reproduce the issue. I recommend checking out how to create a minimal, complete, verifiable example, as it contains many tips on isolating the problem.

Thanks. The problem has grown from 2 seconds to 19 seconds over time as I add more items to the database. There are currently 1,800 objects in the database, most of which are a set of 20 simple strings. My computer internet is horrible but I'll try to put together the minimum code you're asking for.

After doing some work with breakpoints, it seems that it IS getting the info from Firebase within a half a second or so; it must be taking the 19 seconds to render my cardviews or something. I thought I had a recyclerView kind of thing which only required about 5 cards to load at once. I will check this.

I figured it out!!!
Getting financial transaction data from Firebase was NOT the slow point.
The problem was, AFTER getting the data, I ran through all the user's transactions starting with the starting bank balance and adjusted so that each transaction showed then-current bank balance. This apparently takes a heck of a lot of time to do for a couple thousand transactions.
By setting all bank balances to $0.00 and placing the calculations in a background thread, and then updating UI once complete, it now only takes about a second to load (still wait 19 seconds to get current balances to update):
DispatchQueue.global(qos: .background).async {
// do your job here
MIProcessor.sharedMIP.obtainTheBalancesAfter()
MIProcessor.sharedMIP.updateTheMIP()
DispatchQueue.main.async {
// update ui here
self.cardViewCollectionView.reloadData()
}
}

I figured it out!!!
Getting financial transaction data from Firebase was NOT the slow point.
The problem was, AFTER getting the data, I ran through all the user's transactions starting with the starting bank balance and adjusted so that each transaction showed then-current bank balance. This apparently takes a heck of a lot of time to do for a couple thousand transactions.
By setting all bank balances to $0.00 and placing the calculations in a background thread, and then updating UI once complete, it now only takes about a second to load (still wait 19 seconds to get current balances to update):
DispatchQueue.global(qos: .background).async {
// do your job here
MIProcessor.sharedMIP.obtainTheBalancesAfter()
MIProcessor.sharedMIP.updateTheMIP()
DispatchQueue.main.async {
// update ui here
self.cardViewCollectionView.reloadData()
}
}

There is nothing in the code you shared that would explain a 19s load time. If you want us to help, please share enough information for us to be able to reproduce the issue. I recommend checking out how to create a minimal, complete, verifiable example, as it contains many tips on isolating the problem.

Thanks. The problem has grown from 2 seconds to 19 seconds over time as I add more items to the database. There are currently 1,800 objects in the database, most of which are a set of 20 simple strings. My computer internet is horrible but I'll try to put together the minimum code you're asking for.

After doing some work with breakpoints, it seems that it IS getting the info from Firebase within a half a second or so; it must be taking the 19 seconds to render my cardviews or something. I thought I had a recyclerView kind of thing which only required about 5 cards to load at once. I will check this.
