Interstitial

Before start loading Admob you should load Bidmachine ad and save it to store

import BidMachine
import BidMachineAdMobAdapter

func before() throws {
    let configuration = try BidMachineSdk.shared.requestConfiguration(.interstitial)
    BidMachineSdk.shared.interstitial(configuration) { [weak self] interstitial, error in
        AdMobAdapter.store(interstitial)
        self?.after()
    }
}

@import BidMachine;
@import BidMachineApiCore;
@import BidMachineAdMobAdapter;

- (void)before {
    __weak typeof(self) weakSelf = self;
    [BidMachineSdk.shared interstitial:nil :^(BidMachineInterstitial *ad, NSError *error) {
        [BDMAdMobAdapter store:ad];
        [weakSelf after];
    }];
}

Then you can create an admob object and load it

func after() {
    GADInterstitialAd.load(
        withAdUnitID: "unit id",
        request: GADRequest(),
        completionHandler: { [weak self] interstitial, error in
            if let error = error {
              print("Failed to load interstitial ad with error: \(error.localizedDescription)")
              return
            }
            self?.interstitial = interstitial
            self?.interstitial?.fullScreenContentDelegate = self
        }
    )
}

- (void)after {
    GADRequest *request = [GADRequest request];
    [GADInterstitialAd loadWithAdUnitID:@UNIT_ID request:request completionHandler:^(GADInterstitialAd * _Nullable interstitialAd, NSError * _Nullable error) {
        if (error) {
            // fail load
        } else {
            self.interstitial = interstitialAd;
            self.interstitial.fullScreenContentDelegate = self;
        }
    }];
}
