I'm trying to make an API call in my Swift project, but when I run the code the program doesn't reach past if let decodedJson = try? JSONDecoder().decode(JSONStructure.self, from: data) {

I added some print statements to clarify my issue.

I don't get any errors when I run the code either, but I'm guessing that's because I don't have any catch statements. But even when I added that I still didn't get any error. I don't know if this is related to my issue but I tried using try! instead of try? and then I get this error: Initializer for conditional binding must have Optional type, not 'JSONStructure'.

Here is my API call funciton:

Basically, the first two functions (FetchOriginCoordinates and FetchDestCoordinates) take a street name as an input and return the coordinates for it. The coordinates are then used to find a nearby bus stop in the functions FetchOriginID and FetchDestID. These functions return the bus stop ID which is then used in the last function (FetchTrip). In URL used in that functions has four modifiable parameters: originExtId, destExtId, date, and time. The originExtId and destExtId are the values fetched from FetchOriginID and FetchDestID. The date and time parameters correspond to the variables arrivalTime and travelDate.

I only call the FetchTrip function when the Button in the body is pressed. The first time the function is called the variables: self.originLat, self.originLon, self.destLat, self.destLon, self.originID and self.destID are all nil. The second time self.originID and self.destID are nil. And the third time the function works (returns the correct value).

I'm new to swift so I'm not entirely sure why this is caused. But I do believe it's because the nested function continues running without waiting for the other functions to finish. I, therefore, think it has something to do with Closures, but I'm not fully sure how to apply it. Could someone help me?

I'm running into a strange issue with useEffect not noticing the change of values being changed with the context api. I have a fetch that I want to run everytime a certain value is changed and I'm using the context api to manage my state value but it doesn't ever seem to notice. I wasn't having this issue when I was passing props instead of using the context api. Is there a trick to this I'm not using? The console error is: ./src/Components/CustomTrip.js Line 33:12: React Hook useEffect has a missing dependency: 'fetchDistance'. Either include it or remove the dependency array react-hooks/exhaustive-deps

In our docker-compose.yaml we have:

I am attempting to delete a record from DynamoDB using Lambda and API gateway. Currently the Id of the record is passed as a query parameter, which is passed to my deleteRecord lambda function, and used in the delete function of the documentClient.

Currently, I receive errors when trying to delete a record, yet the record is deleted anyway, and I can't figure out why.

When testing on the API gateway, I receive "Internal server error" as a response, yet inspection of the table shows that the item is deleted, and the logs show me the record that has been deleted (as per supplying ReturnValues: "ALL_OLD" in the params passed to documentClient).

When testing on Lambda directly (manually inserting the ID into my dt.delete function), I get the following:

I have a FlatList rendered along with a ListItem so that onPress of a specific row I can get that data inside my ListTrips component. As shown below in my console.warn It will print the data of the selected item.

Component A

I have two components in react native and I'm unable to close a modal from my child component.

ListTrips - Parent

ModalAddTrip - Child

The structure of my code is like a hub and spoke model, with most of my classes instantiated in a Main class that is the hub. In particular, I have a zoom method in the Main class that coordinates calling zoom methods in most of the other classes. In one of the spoke classes, let's call it Buttons, I create some buttons intended to trigger the zoom method in Main, with event listeners added. How might I use these buttons, created in Buttons, to call the zoom method in Main without importing all of Main into Buttons?

Main.js looks something like this:

I'd like to create an array of the modules I am importing into Main.js file. How might I access the object that contains the imported modules?

EDIT To further explain, I am importing multiple classes into a Main.js file containing a Main class. Each of these classes comes from their own individual file, giving me import statements like this:
